Hyper-V Error - Never Before Seen - Google Doesn't even know

Question

I have no idea why this has occurred.. I'm away from home and this is on my home server... All VMs won't start... also any new VMs I create won't start... There's been no changes... I think there was a power outage though... I considered a windows update...
but none have been installed at all....

I won't install any updates just in case as that may only compound the problems..

The only things in the event logs are the messages with the above error.. it doesn't explain further and there doesn't appear to be any extra messages which give more detail.
